Abstract

An electronic device and a control method thereof are provided. The control method of an electronic device includes: acquiring first location information on a projection area of an image projected by the electronic device through a sensor; acquiring second location information on a location where a user is located, through the sensor; and performing at least one of an operation corresponding to a voice input of the user or an operation corresponding to image quality processing based on the first location information and the second location information.

First claim

What is claimed is:

1 . A control method of an electronic device, comprising:
acquiring, through a sensor, first location information of a projection area of an image projected by the electronic device, the first location information being between the electronic device and the projection area; acquiring, through the sensor, second location information on a location of a user, the second location information being between the electronic device and the user; identifying information on a relative location between the projection area, the electronic device, and the user, based on the first location information and the second location information; and performing at least one of an operation corresponding to a voice input of the user based on the information on the relative location and an operation corresponding to image quality processing based on the first location information and the second location information.

2 . The control method as claimed in claim 1 , wherein the performing of the operation corresponding to the voice input of the user includes:
performing a first operation corresponding to the voice input of the user based on identification of the user being located between the electronic device and the projection area according to the information on the relative location; and performing a second operation corresponding to the voice input of the user based on identification of the electronic device being located between the user and the projection area according to the information on the relative location.

3 . The control method as claimed in claim 2 , wherein the performing of the first operation includes:
performing, based on the voice input of the user being received, pre-processing on the received voice input of the user to acquire voice information; and performing the operation corresponding to the voice input of the user based on the voice information.

4 . The control method as claimed in claim 2 , wherein the performing of the second operation includes controlling an external device configured to control the electronic device, so that the external device controls the electronic device to perform the operation corresponding to the voice input of the user, based on a trigger voice input of the user being received.

5 . The control method as claimed in claim 2 , wherein the performing of the second operation includes:
identifying one of the electronic device or an external device to perform the operation corresponding to the voice input of the user, based on the second location information and a third location information received from the external device, and a trigger voice input of the user being received, wherein the external device is configured to control the electronic device.

6 . The control method as claimed in claim 1 , further comprising
identifying the user moving away from a predetermined view angle with respect to the projection area according to the information on the relative location, and performing a keystone function of the electronic device based on the user moving away from the predetermined viewing angle with respect to the projection area.

7 . The control method as claimed in claim 1 , further comprising:
acquiring information on a distance between the projection area and the user based on the first location information and the second location information; and performing at least one of an operation of adjusting a focus of an image projected on the projection area or an operation of correcting the image based on the information on the distance.

8 . The control method as claimed in claim 1 , wherein in the acquiring of the second location information, the second location information is acquired by using location information received from an external device configured to control the electronic device.

9 . An electronic device comprising:
a projector configured to project an image; a sensor; a memory configured to store at least one instruction; and a processor configured to execute the at least one instruction stored in the memory to control the electronic device, wherein the processor is configured to:
acquire first location information of a projection area of the image projected by the projector through the sensor, the first location information being between the electronic device and the projection area;
acquire second location information of a location of a user, through the sensor, the second location information being between the electronic device and the user;
identify information on a relative location between the projection area, the electronic device, and the user based on the first location information and the second location information, and
perform at least one of an operation corresponding to a voice input of the user based on the information on the relative location and an operation corresponding to image quality processing based on the first location information and the second location information.

10 . The electronic device as claimed in claim 9 , wherein the processor is configured to:
perform a first operation corresponding to the voice input of the user based on identification of the user being located between the electronic device and the projection area according to the information on the relative location, and perform a second operation corresponding to the voice input of the user based on identification of the electronic device being located between the user and the projection area according to the information on the relative location.

11 . The electronic device as claimed in claim 10 , wherein the processor is configured to:
perform, based on identification of the user being located between the electronic device and the projection area and the voice input of the user being received, pre-processing on the received voice input of the user to acquire voice information, and perform the operation corresponding to the voice input of the user based on the voice information.

12 . The electronic device as claimed in claim 10 , wherein the processor is configured to:
control an external device configured to control the electronic device so that the external device controls the electronic device to perform the operation corresponding to the voice input of the user, based on identification of the electronic device being located between the user and the projection area and a trigger voice input of the user being received.

13 . The electronic device as claimed in claim 10 , wherein the processor is configured to:
identify one of the electronic device or an external device to perform the operation corresponding to the voice input of the user, based on the second location information and a third location information received from the external device and a trigger voice input of the user being received.
